2. Product Description
2.1 General Description
The Tsunami license-free radios provide a new level of control and convenience in a digital
communications network.
These Tsunami radios provide 100BaseT intelligent bridging between two locations without the delay and
expense of installing cable or traditional microwave.
Because each owner controls the operation of the link, there is no reliance on any outside services.
Tsunami radio operators are able to operate instant links whenever needed, and to be in control of their
own network.
The Tsunami offers two primary benefits:
v CONVENIENCE Easy to install and operate with no user license
requirements or frequency coordination in the USA. (Other
countries may require a user license and/or frequency
coordination).
v CAPABILITY Full transparent Fast Ethernet connections with no
throughput reduction over any line-of-sight distance (within
legal limits of government regulation)
Tsunami radios are ISO Layer 2 Data Link Layer (use MAC address for filtering) devices where they
provide their full stated throughput. At level 2 (bridges) or 3/4 (routers) where hardware plays the major
part, the most common tester is the SmartBits 200 product from NetCom Systems. At Application Layer
7, you will see less than 40% throughput from the maximum capacity measured with SmartBits due to the
increased protocol/software overhead at that level. Layer 7 can be tested with software such as
Ganymede's Chariot or Qcheck product (www.qcheck.net/index.html). Use Qcheck (or equivalent), do
NOT use PING for throughput testing (www.qcheck.net/whyqcheck.html)!
As an example: testing copper CAT5 cable with SmartBits will test 100% throughput (let's say you can
send/rcv a full 100Mbps). At Layer 7 you will be transferring bits at the 100Mbps rate, but approximately
only 45Mbps of user data will transfer (Ethernet has a high overhead of bytes added to each data packet
frame each time you go up a layer). The advantage is the more complex overhead makes the data virtually
resilient to corruption and minor errors (i.e. collisions), it’s easy to reroute and the network can use
inexpensive plug/play devices like hubs/switches instead of multiplexers as used in the telco industry (i.e.
LYNX T1/E1/DS3 radios).
Western Multiplex tests for stated throughput at Layer 2/3 where bridges are defined. At layer 7
(application layer), you may see less than 50% or more depending on the other traffic that may be on the
LAN as this layer is more dependent on the type of data being sent (it does not matter if it's wire, fiber or
any Ethernet bridge -wired or wireless). Another way to look at it: the model 31145 12Mbps (10Mbps
10BaseT+T1/E1 wayside) bridge will test the same as a piece of CAT5 Ethernet cable.

2.3.2 Test Points / Power Indicator
ON This is an LED indication. When lit GREEN, Tsunami is powered.
The Tsunami radio products do not have an on/off switch.
GND This is a test point referenced to chassis ground. This is used in conjunction with the
next two test points to measure voltages related to radio performance.
Note: The ground lug on the Model 28010 ODU must be properly connected to earth
ground.
RSL This is a test point that relates to the Received Signal Level (RSL). The voltage is
measured with a voltmeter (using the GND test point for reference) which corresponds
to the actual power level of the incoming received signal. While the DISPLAY FAR
END button is pressed, this RSL voltage corresponds to the RSL of the far-end radio.
These measurements are used during installation, maintenance and troubleshooting.
Refer to Figure 3-6 in Section 3-20.
RSL is located on the Model 28010 ODU with a weather protected BNC connector.
LOCAL TX
PWR This is a test point which corresponds to the output transmit power of the radio. The
voltage is measured with a voltmeter (using the GND test point for reference) which
corresponds to the actual power level of the outgoing signal. This measurement is
used during installation, maintenance and troubleshooting (software controlled on
Model 28010 with ODU transceiver)
. This voltage only applies to the near-end and does not allow measurement of
the far-end output transmit power, even when the DISPLAY FAR END button
is pressed.
There is a receptacle on the front panel to the right of the LOCAL TX PWR test point
which is an installation adjustment allowing the output transmit power to be increased
or decreased within the radio's specified limits. Using a small screwdriver, this
adjustment is used to set the output power of the transmitter, in accordance to the
path planning. Not available on models with ODU component.
The Tsunami system requires professional installation. Transmitted output
power limits may apply when using this radio. Consult FCC, IC, Western
Multiplex or other regulatory authorities for limits which may apply. See
Section 3.13.1 for details on setting output power.
Do not adjust output power above factory settings.

2.3.6 Connections
RF CONNECTION
The RF port of the Tsunami radio is an N-type female connector that is an integral part of the filter
assembly. The filter assembly occupies nearly the entire top half of the front panel. The N-Type connector
is used to connect the antenna, typically using coaxial transmission line. In some cases, waveguide may
be used as the primary transmission line, in which case a waveguide-to-N adapter is required.
For the Tsunami, 1/2" or 5/8” coaxial cable (LDF4-50 or LDF4.5-50) is
recommended. Coaxial cable that is 7/8” or larger can exhibit moding
at 5.8 GHz and is not recommended for 5.8 GHz radios. For waveguide
transmission line at 5.8 GHz, EW-52 waveguide is recommended. EW-
63 will also work, but may exhibit more loss.
DATA CONNECTION
The connection for the Fast Ethernet interface that carries the signals in and out of the radio is an RJ45
100BaseT wire connection or ST 100BaseT fiber connection.
DC POWER CONNECTION
The input accepts positive or negative DC power at any voltage between 20 and 63 Volts. Optionally, an
AC power adapter can be used.
OPTIONAL CONNECTIONS
There are several connections that are not required for operation, but provide additional facilities to the
user.
EOW
VF
This connection is used to access the electronic orderwire function. This is a facility
for "telephone" style service from one radio to another. A standard electronic
telephone [one with a handset and DTMF (push-button tone) dialing] plugs into this
connector. The user can dial the orderwire address of the far-end radio (or any radio in
the Tsunami network) to establish telephone communication between sites. This
communication does not interrupt or interfere with the other radio communications.
The radio link must be operational to use this facility. The orderwire feature can be
very useful for installation, maintenance and troubleshooting.
This connector is used to link two Tsunami radios at a repeater site for Orderwire
operation. This would allow orderwire "telephone" calls to and from any point in the
Tsunami network. This circuit is 4-wire audio (2xTx and 2xRx)
The Tsunami orderwire circuit can also be connected to other existing
orderwire networks. See Section 3.14.1 for details.
ALARM This connector is used for monitoring alarms electrically. The Form C relays can be
connected to other transmission equipment for monitoring alarm status locally or
remotely.

3.3 Before Installation Task List
There are several tasks that should be accomplished prior to installing the Tsunami radio system.
This section briefly describes the following:
- Site selection
- Line-of-Sight and Path Clearance determination
- Anticipated RSL calculation
- Fade margin calculation
- Availability calculation
- Frequency plan determination
- Power supply planning
- Antenna (and accessories) purchase
Only directional antennas should be used with Tsunami radios.
These are typically flat panel or solid parabolic antennas. Western
Multiplex recommends a maximum beamwidth of 10 degrees for
directional systems.
3.3.1 Site Selection Requirements
The radio site must have:
- access to the appropriate power
- close proximity to the telephone or computer system you wish to interconnect
- line-of-sight to the other radio location with adequate clearance
- location for mounting the antenna

3.3.2 Line-of-Sight and Path Clearance Guidelines
The Tsunami radios will not operate properly unless they have line-of-sight between their
corresponding antennas. The Tsunami radio transmission will not pass through trees or other
obstacles. Factors to consider include:
- Earth curvature
- Future growth of trees
- Height of buildings
In addition to the line-of-sight requirement, a well-engineered path will also have additional path
clearance to allow for signal loss due to partial obstructions, atmospheric ducting and ground
reflections. To maximize radio reception, 0.6 times the first Fresnel zone should be calculated and
this distance added to the path clearance (in addition to trees or buildings).

Tsunami FAMILY
FAST ETHERNET WIRELESS BRIDGES

SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-5
3.3.3 RSL Calculation and Link Budget
The received signal level (RSL) can be estimated using the following formula:
RSL (dBm) = Pout - FL1+ G1 + G2 - FL2 - Lp
where: Pout is the transmitter output power (in dBm)
FL1 is the feeder loss of the transmit side (in dB)
G1 is the gain of the transmit antenna (in dB)
G2 is the gain of the receive antenna (in dB)
FL2 is the feeder loss of the receive side (in dB)
Lp is the Path loss, defined by:
Lp (dB) = 96.6 + 20 log10F + 20 log10D
where: F = Frequency in GHz (2.4 or 5.8)
D = Distance of path in miles
This link budget is very important for determining any potential problems during installation. If you
have calculated the expected RSL, you can see if it has been achieved during installation, and
troubleshoot if necessary.
In the USA and Canada, Tsunami radios may be installed with any gain directional
antennas but with a total system limit of +30 dBm EIRP for the 5.3 GHz transmitter
channel frequencies. 5.8 GHz transmitters have an EIRP limit of +53 dBm. For the
equation above, replace the Pout - FL1+ G1 by the EIRP limit.

PAGE 3-6 SECTION 3: INSTALLATION & ADJUSTMENTS
3.3.4 Fade Margin Calculation
The fade margin is the difference between the actual received signal and the radio’s threshold. Using
the formula provided in Section 3.3.3, the anticipated RSL can be calculated. Compare this RSL to
the specified threshold of the Tsunami radio (shown in Section 2.2) and calculate the fade margin
as the difference between the two signal levels.
3.3.5 Availability Calculation
Availability of the microwave path is a measure of the percent of the time that the link will operate
without producing an excessive BER due to multipath fading. In the absence of direct interference,
availability is affected by the following:
- Path length
- Fade margin
- Frequency (5.3 or 5.8 GHz in the case of these Tsunami radios)
- Terrain (smooth, average, mountainous)
- Climate (dry, temperate, hot/humid)
Depending on the type of traffic carried over the link, the system designer may wish to design for a
specific availability. For example, if the data or voice traffic that is carried by the radio is critical then
it may be designed for a very high availability (e.g. 99.999% or 5.3 minutes of outage per year). To
improve availability, for example, the fade margin can be increased by making the path shorter, or
by using higher gain antennas in conjunction with lower loss feeders (by using high quality
transmission line or shortening feed length).

SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-7
3.3.6 Frequency Plan Determination
When configuring radios in a hub or repeater configuration, careful engineering of the Tsunami radio
frequency plans and antenna locations should be performed in order to minimize potential
interference between the nearby radios. As a rule of thumb, do not place identical frequency plan
radios (e.g. two “A” channel radios) at the same site. In most cases, it is desirable to use a different
frequency plan (e.g. A versus B). However, with careful engineering, placing more than one radio of
the same frequency channel plan at the same site is easily accomplished. In fact, the Tsunami
frequency plan is designed to allow complex hub configurations that may require re-using the same
frequency plan. When designing these types of configurations, antenna size and antenna location
are critical. If identical channel plans must be used at the same site, the same radio channel (e.g.
A1 and A1) should be used at a site to minimize interference. Using alternate channels (e.g. A1 and
A2) is less likely to be successful (and therefore not recommended) due to the high level of
transmitter to receiver isolation required from the antenna system.
Sometimes it is required to locate the Tsunami radio nearby a transmitter that is the same as, or
close to the Tsunami receive or transmit frequencies. In this case, the Tsunami terminal that should
be placed closest to this interfering transmitter should be the specific terminal with the receive
frequency which is furthest from this unwanted transmitted frequency. This approach minimizes the
potential of interference. While interference conditions are rare when using the Tsunami radios,
cases of interference may be overcome by exchanging the radios from end to end or simply
reinstalling a different filter unit (if applicable), as described in Section 4.2. In some cases, changing
frequency plans (e.g. from A to B) can also help mitigate any interference.
Section 4.8 of this manual describes interference
countermeasures in further detail.

PAGE 3-8 SECTION 3: INSTALLATION & ADJUSTMENTS
3.3.7 Power Supply Planning
The Tsunami radio must have access to a supply of appropriate power, either DC or AC (if the AC
adapter option has been ordered). The Tsunami can be powered from a DC battery system, or from
a solar or generator power plant, usually with battery reserves. Typically either a positive or negative
ground 24 or 48 volt supply is used. For DC, be sure the cable is of sufficient gauge to carry the
necessary current and it is less than three (3) meters (9.75 feet) in length.
Before installing the radio, plan for the continuous power consumption needs in accordance with the
specifications given in Section 2.2 of this manual. It is also wise to plan for backup power for critical
communication circuits (including the Tsunami radio). Backup power allows the radios and
associated equipment to continue operation when primary power is interrupted.
3.3.8 Antenna Planning
Using the path planning tools and equations presented in the Product Guide, proper antenna size
can be determined which will yield the desired path performance. In general, the larger the antenna
that is used with the radio, the better the link will perform. Larger antennas have narrower
beamwidth and higher gain, which will yield better link performance (higher fade margin, better
availability) and improve immunity to interference (due to the smaller beamwidths). However, larger
antennas are more costly to purchase and install than smaller antennas, in some cases requiring
special equipment for installation. All of these factors should be taken into consideration when
selecting an antenna. Consult the Product Guide for more details on selecting antennas.
Recommended Antenna
Size Gain / 3 dB Beam Width
2 ft 29 dB / 6°
4 ft 35 dB / 3°
6 ft 38 dB / 2°
8 ft 41 dB / 1.5°
10 ft 43 dB / 1.3°
In areas where transmitted output power restrictions apply, the
use of larger antennas will maintain the benefit of narrow
beamwidths and receive gain. However, output power may need to
be reduced to meet regulations. (See Section 3.13.1)
Prior to installation, the specific antenna location and mounting should be determined. This
advanced planning also yields the transmission line requirements.
Only directional antennas may be used with these radios.

3.6 Mounting the Tsunami
The Tsunami radio can be mounted at any height in a standard 19-inch rack. Blank rack-mounting
spaces above and below the Tsunami are recommended, especially if the surrounding equipment
dissipates a considerable amount of heat (over 40W).
The Tsunami radio may be set up for mounting with the front edge projecting from the front face of a
standard 19-inch rack using the rack mounting brackets enclosed with the screws in the Accessory
Kit (4 per bracket). The rack mounting brackets may be reversed, in order to install for flush or
cabinet mounting if preferred. Depending on rack configuration, it may be necessary to remove the
four adhesive backed rubber feet on the bottom of the unit.
The Tsunami radio has internal fans which intake and exhaust
on the left and right sides of the chassis. When rack mounting,
it is important to leave a small gap between the outer edges of
the radio and the inside edge of the rack.
The Tsunami radio may alternatively be placed on a table or shelf
attached to a wall. Because of the low weight of the Tsunami, any
mounting option other than rack mounting will be less secure.

3.7 Power Connection and Wiring (Models w/o ODU)
There is no ON/OFF switch on the Tsunami. As soon as
power is applied, the equipment will be operational. This
means that there can be up to 1W of RF power present at
the antenna port. The antenna port should be terminated
before power is applied.
Power is connected using the DC power plug contained in the Accessory Kit. Use Table 3-A or 3-B
along with the associated diagram of Figure 3-4 or 3-5 to connect the DC power cables. For
example, for a negative DC power input, use Table 3-A and Figure 3-4.

Connect the power cable with adequate current rating (minimum of 20 AWG) to the terminals shown
on the removed (not plugged into the radio) DC power plug using the screw connections. The
recommended minimum current rating of external fuses and cables is 3 Amps. The Tsunami radios
consume less than 1 Amp at ±48V and less than 2 Amps at ±24V. Be sure the DC power cable is
less than 3 meters (9.75 feet) in length.
Each Tsunami terminal should be externally fused separately
with a 5 Amp maximum fuse. The DC power cable must be less
than three (3) meters in length.
If using negative power, connect the negative voltage to pins 1 or 6. Connect the ground return
connection to pins 3 or 4. See Figure 3-4.
If using positive power, connect the positive voltage to pins 3 or 4. Connect the ground return
connection to pins 1 or 6. See Figure 3-5.
The ground connection is available at pins 2 and 5. Either pin may be used to ground the return
side of the power supply. Do not ground both sides of the power supply.
Proper grounding, either through the chassis and/or the power
supply, can be very important for protection from lightning. A
grounding screw hole is provided on the rear panel.
The ground connection may be left floating if the power supply is
referenced to ground externally and to avoid ground loops in
some configurations. However, this may not provide adequate
grounding for lightning protection.
Use a DVM (digital voltmeter) to verify voltage and polarity on the DC power plug.
Do not connect the DC power plug to the rear of the Tsunami
terminal until a load is connected to the antenna port (either an
RF pad, or an RF cable and antenna).

3.10 Antenna Installation & Alignment (Models w/ODU)
The antenna installation consists of permanently mounting the antenna to the mast/pole/tower and
then attaching the ODU mounting plate and then the ODU itself to the mount. The antenna and
ODU assembly must be mounted outdoors on a tower, building roof, or other location that provides
line-of-sight path clearance to the far-end location. In general, antennas smaller than 2.0 feet
diameter are not recommended.
Antennas should be ordered with the suitable mounting kit specific to the site requirements. The
antenna must be very rigidly mounted, with adequate room for azimuth and elevation adjustment
from the rear. The antenna polarization must be the same at both ends of the link, either vertical or
horizontal. The mounting kit includes the details on how to mount and adjust azimuth and tilt. Here,
the details on how to mount the adapter plate and ODU are described. Be sure to have all the
necessary tools available (see section 3.4) before mounting the antenna and ODU.
In general, antenna mountings require a support pipe to which upper and lower support brackets are
attached with “U” bolts. The antenna and optional elevation and azimuth adjustment rods are then
mounted onto the support brackets. The whole structure must be adequately grounded for lightning
protection. The antenna system must always be installed according to the manufacturer’s
instructions.
Unless special test equipment is available, two operating radios are required to align the antennas.
The antenna is coarse aligned using visual sighting and then fine aligned using the receive signal
level (RSL) voltage of the radio. See figure 3-11.
The RSL voltage reading can still be used to peak antennas
even if the radios have not synchronized, however far-end RSL
cannot be measured from the near-end terminal until radios are
synchronized.
INSTALLER CAUTION: Antenna(s) used for this transmitter must be fixed-
mounted on outdoor permanent structures with a separation distance of at
least 1.5 meters from all persons during normal operation. Users and
installers must be provided with antenna install
ation instructions and
transmitter operating conditions, including antenna co-
location requirements
of 1.1307(b)(3), for satisfying RF exposure compliance.

3.10.2 Course Antenna Alignment
To coarse-align the antenna, first set it for flat elevation (no up or down tilt) using a spirit level. Then
point it at a heading marker obtained using a compass/GPS (magnetic corrected) back-bearing from
an adjacent location, (ideally, 100 feet or more away from the antenna).
If a heading marker cannot be set sufficiently far away (for example when on a city building roof or
looking through a window) then a rough azimuth setting can be obtained by sighting along the
antenna feed.
It should be verified that both antennas are on the same
polarization by using the manufacturer’s instructions. Otherwise
the RSL will be approximately 25 to 30 dB below the calculated
level.
Most antennas will also need fine alignment obtained using an operating link because it is very
important to maximize the receive RF signal level at each end of the radio link.
Read Section 3.9 before applying DC power to the radio.
Once the coarse alignment has been set-up at both ends, then the link can be powered and some
level of reliable communication established. The voltage at the ODU RSL test point (BNC connector)
should be measured with a DVM to determine the relative receive RF signal level.
For the fine alignment, adjusting first the azimuth and then the elevation of the local antenna will
maximize the RSL voltage. Then, the far antenna is aligned in the same way, using the RSL voltage
of its local radio ODU.
When aligning antennas it may be convenient to allow direct visibility to the technicians aligning the
antenna.
An orderwire telephone will provide end-to-end voice communications
once radios are synchronized. Synchronization usually can be
accomplished by coarse alignment only. After synchronization, the
orderwire phones can be used to communicate between radio sites for
antenna fine alignment. The phone interconnect cable can be
extended to the antenna when desired.
The larger the antenna size, the more critical alignment becomes: for example, with a 2 foot dish,
the antenna can be moved ±3 degrees off the correct heading before the receive signal level drops
by 3 dB. This compares with a 6-foot dish which may only be moved ±1 degree for the same
degradation.
The graph shown in Figure 3-13 shows the typical variation of RSL voltage as the receive signal level
is increased from threshold to a higher level. There is some variation between receivers, but an
approximate estimate of the potential RSL value may be made using this figure.

Tsunami FAMILY
FAST ETHERNET WIRELESS BRIDGES
December 2001
PAGE 3-26 SECTION 3: INSTALLATION & ADJUSTMENTS
Use the Factory Test Data Sheet shipped with your terminal to obtain the
best estimate of your RSL.
Above 0 dBm RSL, the receiver may produce errors: however this level is rarely likely to be
exceeded. A link budget calculation should be made to calculate the anticipated RSL as described
in Section 3.3.3. During anomalous propagation conditions, the RSL may fade but will not increase
up more than 10 dB (except in unusual very long paths which may fade up by 15 dB).
Antenna alignment should enable the RSL to be peaked to the
level calculated in the link budget. If the RSL is peaked but is
approximately 20 dB below the calculated level, then it is likely
that the antennas are aligned on a sidelobe of the antenna's
radiated signal. In this case, the antennas should be rotated in a
wide arc until the main lobe is located. (Other possible causes of
low RSL are path obstructions, loss in connectors, adapters and
pigtail jumper cables or different antenna polarization at each end
of the link.)

3.11 Antenna Connection
The Tsunami radio is equipped with an N-type female connector at the antenna port located on the
rear panel. A short length (~6 feet) jumper cable such as RG-214 coax (or “pigtail”) fitted with two N-
type male connectors can be used to connect the antenna port to the antenna transmission line
(see Section 3.9). The recommended cable type for a jumper is RG-214.
A low loss 50-ohm cable (for example LDF4-50 1/2 inch coax) or EW-52 waveguide is
recommended for the antenna transmission line between the top of the rack and the antenna. The
return loss presented by the transmission line at the top of the rack should be as high as possible
(20 dB, minimum recommended). The length of the antenna transmission line should be kept as
short as possible (to minimize losses).
To minimize feeder losses, the use of elliptical waveguide is recommended (typical loss is 1.25
dB/100 ft) for feeder lengths in excess of 200 feet. Depending on path length and feeder length, 1/2
inch or 5/8 inch coax cable can be used.
For the Tsunami radio, 1/2” or 5/8” coaxial cable (LDF4-50 or
LDF4.5-50) is recommended. Coaxial cable 7/8” or larger can
exhibit moding at 5.8 GHz and is not recommended for 5.8 GHz
radios. For waveguide transmission line at 5.8 GHz, EW-52
waveguide is recommended. EW-63 will also work, but may
exhibit more loss.
Do not use right angle N-type connectors with the 5.8 GHz
Tsunami radios: they may present high loss at 5.8 GHz. Do not
use a low quality N-type jumper cable with the Tsunami. Some
cable types, such as RG-8, may have high loss at 5.8 GHz.

3.12 Transmission Line Connection
The transmission line feeder (such as LDF4-50 1/2 inch coax cable or EW-52 elliptical waveguide)
should be prepared first by cutting to the approximate length (allowing some excess) and installing
the appropriate connector on the antenna end.
The prepared transmission line is then pulled through the cable ducts, trays or conduit (as required)
to the antenna, while being careful not to kink or damage the transmission line in any way.
The transmission line should be supported in a tray on horizontal runs and by hangers on vertical
runs. Hangers should be spaced according to the manufacturer’s instructions (typically every 5 feet
under conditions of no ice and not greater than 85 mph winds).
The transmission line should be grounded using the manufacture’s recommended grounding kit.
Grounding kits attach to the outer copper conductor. Grounds must be installed at the antenna, at
the bottom of the tower (if applicable) and where the transmission line enters the building. Long
transmission line runs should be grounded every 100 feet. In areas of high incidence of lightning,
dissipaters should be attached to antennas. In addition, coaxial, in-line, spark-gap type, lightning
suppressors should be added at the bottom of the coax cable before entering the
building/enclosure.
Any in-line lightning protection device must be rated for the
operating frequency of the Tsunami (5.3/5.8 GHz).
After installation, the transmission line is terminated with an N-type male connector/adapter
attached at the equipment end. For waveguide, this typically requires a CPR-to-N adapter.
Prior to operation, the electrical integrity of the transmission line, including all connectors, can be
checked with a simple DC check between the center conductor and outer conductor. (This is
neither possible, nor required for waveguide).
The transmission line should ideally be connected directly to the antenna at one end and to the
Tsunami antenna port at the other end. However, short RG-214 type pigtail jumper cables may be
required to avoid sharp bends in the transmission line to limit stress on either connection.
7/8 inch coax cable or larger is not recommended for use at 5.3
GHz and higher frequencies.
Do not use right angle N-type connectors with the 5.3 or 5.8 GHz
Tsunami radios: they may present high loss at 5.3 or 5.8 GHz.
Do not use a low quality N-type jumper cable with the Tsunami.
Some cable types, such as RG-8, may have too high a loss at
5.3 and 5.8 GHz.

3.13 Antenna Installation & Alignment
The antenna installation consists of permanently mounting the antenna outdoors on a tower,
building roof, or other location that provides line-of-sight path clearance to the far-end location. In
general, antennas smaller than 2 feet diameter are not recommended for urban areas due to their
wider beamwidths, which results in higher interference susceptibility.
Antennas should be ordered with a suitable mounting kit specific to the site requirements. For
example, specifying round or angle tower leg adapters, or a roof tripod as necessary.
The antenna must be very rigidly mounted, with adequate room for azimuth and elevation
adjustment from the rear.
The antenna polarization must be the same at both ends of the link, either vertical or horizontal.
In general, antenna mountings require a support pipe to which upper and lower support brackets are
attached with “U” bolts. The antenna and optional elevation and azimuth adjustment rods are then
mounted onto the support brackets. The whole structure must be adequately grounded for lightning
protection. The antenna system must always be installed according to the manufacturer’s
instructions.
Unless special test equipment is available, two operating Tsunami terminals are required to align
the antennas. Alternatively, a CW generator may be used to transmit a signal toward the end under
alignment.
The antenna is coarse aligned using visual sighting and then fine aligned using the receive signal
level (RSL) voltage of the Tsunami.
The RSL voltage reading can still be used to peak antennas
even if the radios have not synchronized, however far-end RSL
cannot be measured from the near-end terminal until radios are

all persons during device operatio
n to comply with FCC and other regulatory
RF Exposure requirements. Installers should contact the manufacturer for

of its local Tsunami radio.
When aligning antennas it may be convenient to run two wires from the RSL and ground test points
to the antenna so that the voltmeter reading is directly visible to the technicians aligning the
antenna. Also, a cellular telephone or two-way radio may be useful for coordinating alignment
activities between both ends of the link. Once the radios are coarse aligned and synchronized, the
built-in orderwire phone service can also be used to coordinate alignment between both ends of the
link.
An orderwire telephone will provide end-to-end voice communications

3.15 System Turn-up to Service
1. Prior to installing the system, it may be desirable to perform a back-to-back test of the
Tsunami radio pair. Consult Section 4.9 for further details. Back-to-back testing is a simple
way to verify that the Tsunami radios are fully operational before they are installed. Installation
adds several variables (such as antenna alignment) which can lead to system turn-up delays.
Also, during back-to-back testing, the DIP switch settings and some connections can be
tested. This step can eliminate a majority of troubleshooting once the radios are installed.
A cellular phone or two-way radio system (walkie talkie, CB,
mobile radio) can be very useful during installation. These
can be used for temporary near-end and far-end
communications between the installation personnel at one
site and installation personnel at the other site while installing
the system. These can also be helpful for communication
between a person at the top of a very tall tower and ground
personnel.
The Tsunami radio incorporates an internal Orderwire feature
that provides end-to-end “telephone” style communications.
However, the link must be partially operational to use this
feature. In lieu of, or in addition to the use of cellular phones
or two-way radio, this Orderwire feature can also be very useful
for installation, but typically cannot be put into service until
step 8 or 9 of this procedure is completed.
2. Perform a general alignment of the antennas on both ends of the path using binoculars,
compass or other related tools. It is important to have the antennas aligned as accurately
as possible before putting radio traffic over the link. This will help in getting the system
running more rapidly.
3. Connect the transmission line to the antenna, and feed it to the Tsunami radio location.
Connect the opposite end of the transmission line to the N-type female connector located
on the filter assembly which occupies the top half of the Tsunami rear panel. The
connection must be terminated into an antenna or a load before DC power is applied to the
radio.
4. Verify that the same channel plan (e.g. A, B) as the near-end radio, and the opposite Tx
and Rx frequencies (e.g. A1 and A2 make up a matched pair of radios).
5. With the DC power source active, but not plugged into the Tsunami radio, using a
voltmeter, confirm that the DC mating connector has the proper power connections in
accordance with Section 3.7. Verify the polarity and the absolute voltage on all pins. Verify
ground connection for power.
6. Connect power to the Tsunami radio. Verify that the IDU’s Front Panel “ON” LED indication
is illuminated. This confirms that power has been properly applied.
Ensure that the RF Antenna port connection is properly
terminated before applying power to the Tsunami terminal, as in

step 3.
When the Tsunami radio is initially powered-on, some alarm
conditions may be present. This is normal and alarms can be
ignored at this time.
7. Place a voltmeter across the GND and PWR front panel test points. See Figure 3-15 for
voltage setting information and Table 3-E for typical output power levels for given cable
lengths where EIRP limits apply. If necessary, use a small screwdriver at the front panel
receptacle to adjust the output power of the local transmitter in accordance with the path
analysis calculations. The recessed potentiometer is rotated clockwise to increase transmit
output power and counter clockwise to decrease transmit output power. After verifying
correct setting of the transmit output power, disconnect the voltmeter. Place the cover cap
found in the installation accessory kit over the front panel receptacle.
The Tsunami radio requires professional installation. With some
Tsunami models, in certain countries, there may be Effective
Isotropic Radiated Power (EIRP) limits which dictate the
maximum output power that the Tsunami radio can transmit given
the transmission line loss and the gain of the antenna. Consult
with appropriate government agencies or Western Multiplex if
there is any question regarding maximum output power allowed.
Do not adjust output power above factory settings.

For precision measurement of transmit output power, it is best to
connect an RF power meter to the antenna port. The PWR port
voltage may not provide enough precision. This is especially
important where EIRP limits apply to the installation.
In cases of no EIRP limits, the radio transmitter output power
should be left at the factory setting, except for very short paths
using very high gain antennas, where excessive power may not
be advised.
Don’t forget that the RF output port should be terminated at all
times when power is applied to the Tsunami radio. Therefore,
disconnect power to the radio before connecting a power meter
and reapply power once connected. Often, an RF power meter
may have a limit to the input power that it can measure without
damage. It is advised to place a calibrated fixed value RF
attenuator (typically 20 dB or more) between the Tsunami radio
and the power meter to assure proper operation and safety for the
RF power meter. The value of this fixed attenuation can then be
added to the value of the RF power meter reading to obtain the
actual Tsunami radio transmitter output power.
8. Connect a voltmeter across the GND and RSL front panel test points. This voltage reading
corresponds to the Received Signal Level (RSL) of the near-end radio. In other words, RSL
is the “amount” of signal the near-end radio is receiving from the far-end radio. Since the
antennas have not been finely aligned, it is not expected at this time that the RSL will read
very high. However, at this point it can be verified that some communication is taking place
between the two Tsunami terminals. Use the RSL voltage reading to align the antennas.
Align one antenna at a time in accordance with Section 3.13. Complete alignment of both
ends of the radio link before going further.
The RSL voltage output on the radio's front panel will output a
voltage over the usable range of the radio. Refer to Figure 3-14.
The Tsunami radio has a unique feature of allowing measurement of the far-end RSL from
the near-end radio. This is only possible if the Tsunami radios are communicating (the RSL
is above threshold). The far-end RSL can be used to verify that adjustments to local
antenna alignment are corresponding to the far-end radio reception. Far-end RSL is
measured by pressing and holding the DISPLAY FAR END front panel button. While this
button is held, the RSL voltage indicates the RSL of the far-end radio. RSL of both ends
should be verified to be within approximately 2 dB of predicted value (see Section 3.3.3).
There are several factors that can contribute to low RSL:
- Incorrect antenna alignment (aligned on a lobe and not on the main signal)
- Improper polarization alignment of antennas (horizontal vs. vertical)
- Transmission line problems (loose connections, bent or damaged cables, lossy adapters)
- Path obstructions (trees, buildings, hills, etc.)

- Path clearance (line-of-sight, earth curvature, Fresnel zone, diffraction and partial
obstruction)
- Weather (inversion layers, ducting and multipath)
- Antenna feed (coaxial/connector) problem
The Tsunami radio requires professional installation. Don’t
forget that the transmitter output power adjustment on the
Tsunami radio effects the RSL. Depending on EIRP limits (if
any), path distance, and antenna gain, you may need to adjust
the output transmit power to the proper level before putting the
radios in service.
If radio synchronization has been established, the radio link
may be able to provide some limited communications over the
link. It can be helpful to establish voice communications from
one end of the radio link to the other using the Orderwire
feature of the Tsunami radio.
If RSL is lower than anticipated, recheck the path clearance and transmission line as these are the
typical causes of low RSL. Radio operations can be verified by connecting radios back-to-back with
attenuators (40-60 dB), (see Section 4.9). If the problem remains, consult Section 4 of this manual
for troubleshooting techniques which will help determine the source of the problem.
9. Once radio performance is verified and acceptable, the Tsunami radios can now be put into
service with the intended Fast Ethernet traffic. Connect to the LAN or computer using the
RJ45 (wire) or ST (fiber) 100BaseT connector. With Fast Ethernet traffic applied in both
directions, all front panel LEDs, except for POWER and the data TXD/RXD lights should be
off. If any other LEDs are on, consult the trouble shooting sections of this manual.
10. Now that the link is operational, other services can be connected including T1 (DSX-1),
Orderwire, Diagnostics, Alarms and Aux Data (Service Channel). Consult Section 3.17 for
details on these connections.

3.16 Output Power Adjustment
The Tsunami radio requires professional installation. In certain cases, it is necessary to adjust the
output power lower (never higher) from the factory setting, for example:
v to meet EIRP (effective isotropic radiated power) limits.
v to avoid exceeding the maximum far-end RSL of -30 dBm.
v to coordinate a hub or repeater location.
To ensure maximum protection of the radio circuits, always
ensure the antenna connector is terminated when power is
applied. Never adjust output power above factory settings.
For precise measurement of transmitter power, a calibrated RF power meter (such as the HP 435B
with Power Sensor HP8481) is recommended. This power sensor can be connected directly to the
output of the radio without exceeding the power rating. With some power meters, it may be
necessary to place a calibrated in-line fixed attenuator between the radio antenna port and the
power meter so as to not exceed the power meter’s maximum input level. Thruline power meters do
not operate at Tsunami RF frequencies.
If adjusting the output power to meet an EIRP limit, it will be first necessary to calculate the overall
system gains and losses, including feeder losses for the type of transmission line installed and the
antenna gain. Also refer to Table 3-E for transmitter output power settings where installed with
various transmission line lengths and antenna sizes. You may determine the radio transmit power
for EIRP limited installations by the following equation:
Tx Power (dBm) = EIRP Limit(dBm) + Feeder Loss(dB) - Antenna Gain(dB)
For the US and Canada, a +30 dBm EIRP limit applies for the
dual band (5.3/5.8 GHz) Tsunami radios and a +53 dBm EIRP
limit applies for the single band (5.8 GHz) Tsunami radios.
Output power may be adjusted using a small screwdriver and rotating the potentiometer which is
recessed behind the front panel. Clockwise rotation increases output power while counter-clockwise
rotation decreases output power.
In lieu of a calibrated RF power meter, the PWR test port voltage can be used to estimate the
output power. Figure 3-15 illustrates the voltage reading for various output power levels. The factory
test data sheet should be used to establish a more precise setting of this adjustment.
After setting the correct output power, place the cover cap
found in the installation accessory kit over the front panel
receptacle.
FCC EIRP limitations:
Models that have transmitters that use the 5.3 GHz band should not exceed a total of +30 dB
E.I.R.P.
Models that have transmitters that use the 5.8 GHz band should not exceed a total of +53 dB

3.17 Additional Connections
There are additional customer connections which are optional and are not required to make the
Tsunami operational but may prove useful.
3.17.1 Orderwire Connection
Orderwire is a “telephone” type wayside service which allows users of the Tsunami radio to
establish voice communications from one radio to another, either directly to the companion far-end,
or through a repeater configuration, or several repeater configurations.
Telephone connection specifications:
REN (Ringer Equivalency Number) 1.0 B
DTMF tones within ±1.5% of nominal freq.
Ringing Voltage 48 VDC, typical
(Ringing voltage is adequate for modern solid state ringers,
NOT for the older mechanical type ringers)
This Orderwire service does not affect the normal radio transmission of traffic. Refer to Section 2.3.5
for the telephone specifications. For simple near-end to far-end communications, follow the steps
below:
1. Using a standard RJ-11 telephone cable, connect a standard electronic telephone (a touch
tone phone, complete with dialer; a handset by itself will not work) to the Orderwire
connector on the Tsunami front panel. This connector is wired identically to a standard two-
wire telephone jack, see Figure 3-16 for details.
2. With a telephone connected to each Tsunami terminal on opposite ends of the link, either
telephone can be used to “dial-up” the far-end location. The far-end terminal’s internal ringer
and the connected telephone will ring, and if answered, two-way full-duplex voice
communication is established.
If using the Orderwire or Network management functions, all
Tsunami radios connected must have unique address settings
(telephone numbers).
4. If the Tsunami radios are connected in a repeater configuration, Orderwire services can be
established to all Tsunami terminals in the network by implementing a connection of their rear-
panel connectors between repeater terminals. At the repeater site, a cable can be connected to
the two Tsunami terminals between their rear panel VF 9-pin connectors as shown in Figure 3-
16. With this cable in place, the Orderwire function will operate at terminals at each end of the
repeater and at the repeater site. This function can be continued through several repeater sites
if desired. For hub connections of 3 or more Tsunami radios at the same site, an external 4-wire
bridge is required to connect all radios to the orderwire.
The orderwire system can be integrated with orderwire equipment
supported by many other vendors. If your existing orderwire

network uses 2 digit addressing, and 0 dBm VF interface, it can be
connected to a Tsunami as shown in Figure 3-16.
Dialing a V (star key) on the orderwire telephone implements an “all call”
feature which rings all connected radios. Also, if a phone anywhere in the
connected network has accidentally been left off-hook, the # (pound key)
key can be used to mute all off-hook handsets until they are placed on
and off hook again.
The orderwire operates like a “party line”. All telephones provide
communication to all other telephones in the connected network. Even if a
particular telephone does not ring, it can still be used to talk and listen to
any ongoing orderwire activity if the orderwire is in use at other terminal
locations.

3.14.3 Configuration Port Operation
The “Config” Port is used to retrieve diagnostic information and to configure additional features within
the Tsunami radios by means of a computer connection via SERIAL interface. Also can be used as
an RS-232 port to download the latest revision radio operation software.
The config port allows connection of RS-232 devices to receive status of the Tsunami radio and
provide configuration.
For RS-232 diagnostics connection (Section 4.11) to the Tsunami radio, connect the serial device
(modem, computer, terminal) to the male 9-pin subminiature connector in accordance with Figure 3-
18.
Figure 3-18: RS-232 Config Port Connections
Pins 6 through 9 must not be connected for RS-232
communications to operate properly.

3.17.4 AUX DATA (Digital Service Channel) Connection
The AUX DATA port is a separate wayside serial port which can be configured to allow the
connection of any user serial data (to 9600 baud, 1 start/stop bits) through the radio network.
Connection to the AUX DATA port is an RS-232 serial interface, identical to the config port (see
Section 3.17.3). This port does not affect the Ethernet traffic on the Tsunami radio.
The following HELP screen will be presented. Type one of the listed commands.
In this example, the setIP command was initiated.

3.17.5 T1 (DSX-1) Interface Connection
The Tsunami radio also provides a wayside T1 connection. This connection allows for standard DSX-
1 connect of voice circuits without affecting the Ethernet traffic. A standard RJ-48c connector is
provided for this connection.
3.17.6 CEPT-1 (E1) InterfaceConnection
The CEPT-1 interface connection provides a balanced (120 ohm) wayside E1 connection.
If an unbalanced 75 ohm connection (RJ45) is required, an optional
balun will provide this interface. If you can not locate these baluns
(balanced/unbalanced) devices, please consult the factory.
Additional external lightning protection devices are recommended for
all user connections if the radio is installed in an area prone to
lightning.
3.17.7 NMS Interface Connection
The NMS connection provides connection for the network management system. This allows an
HTML interface to the Tsunami radio for purposes of monitoring, configuration and security settings.
This connection is an RJ-45 style connection and complies to standard 10BaseT interface.
Typically, the installer or manager will connect to the NMS with a stand-alone computer to initially
configure the radio prior to installation. If IP addresses and security are set properly, the connection
can also be used as an out-of-band connection for radio management. Alternatively, if the 10BaseT
is connected to a network, or combined with the 100BaseT traffic on the link, via an external 10/100
switch, hub or router, full wireless NMS can be achieved for all radios in the network.
The factory default IP address is set to 10.0.0.1. To reset the radio back to the factory default, Hold
down the far-end test button while powering up the radio. Release the switch after 6 seconds.
More details on the NMS connection can be found in Section 4
of this manual. In the future, this connection will also allow
NMS via SNMP (Simple Network Management Protocol) in
addition to the HTML interface that is presently supplied.
Consult factory for details or assistance with NMS
connections, if required.
Note: Multicasting with in-band connection may cause collisions in the data stream.
